Introduction
At the beginning of the 20th century,
U.S. women were most likely to die
from infectious diseases and
complications of pregnancy and
childbirth. In 2006, the chronic
conditions of heart disease, cancer, and
stroke accounted for 55 percent of
American women's deaths, and they
continue to be the leading causes of
death for both women and men.
Women have a longer life expectancy
than men, but they do not necessarily
live those extra years in good physical
and mental health. On average, women
experience 3.1 years of reduced physical
functioning at the end of life, and in
2008, 14 percent of women aged 18 and
older who were surveyed said they were
in fair or poor health.
The Agency for Healthcare Research
and Quality (AHRQ) supports research
on all aspects of health care provided to
women, including:
- Enhancing the response of the health
system to women's needs.
- Understanding differences between
the health care needs of women and
men.
- Understanding and eliminating
disparities in health care.
- Empowering women to make well-informed
health care decisions.
This summary presents findings from a
cross-section of AHRQ-supported
research projects on women's health
published January 2006 through
December 2009. An asterisk (*) at the

Cardiovascular Disease
Heart disease is the number one killer of
women in the United States. More than
one-fourth of all deaths among U.S.
women in 2006 were due to heart
disease, which usually occurs about 10
years later in life in women than in
men. Heart disease mortality differs
substantially among women of different
races, and almost two-thirds of women
who die suddenly of coronary heart
disease have no previous symptoms.
- Association found between cardiac
illness and prior use of a certain type of
breast cancer drug.
According to this 16-year study of
nearly 20,000 women with breast
cancer, those who received
chemotherapy that included
anthracycline had a higher incidence of
congestive heart failure,
cardiomyopathy, and dysrhythmia than
women who received other kinds of
chemotherapy or no chemotherapy. For
example, the probability of experiencing
congestive heart failure in year 10 was
32 percent for women who received
anthracycline, compared with 26
percent for women who received other
types of chemotherapy and 27 percent
for those who received no
chemotherapy. Du, Siz, Liu, et al.,
Cancer 115(22):5296-5308, 2009
(AHRQ grant HS16743).
- Women are more likely than men to
experience delays in emergency care for
cardiac symptoms.
Researchers examined time-to-treatment
for 5,887 individuals with suspected
cardiac symptoms who made a call to
911 in 2004. They found that on
average, women arrived at the hospital
2.3 minutes slower than men. Factors
increasing the likelihood of delay
included evening rush hour travel,
bypassing a local hospital, and living in
a densely populated neighborhood.
Even after adjustments were made for
these factors, women were significantly
more likely than men to be delayed.

Cardiovasc Qual Outcomes 2:9-15, 2009
(AHRQ grants HS10282, T32
HS00060).
- Postmenopausal women with
metabolic syndrome are at increased
risk for a cardiovascular event.
Researchers used data on 372
postmenopausal women to investigate
the effects of using two competing
clinical definitions of metabolic
syndrome on their usefulness in
identifying women at high risk of future
heart attacks or stroke. Metabolic
syndrome—a combination of high
blood pressure, elevated blood glucose,
abnormal lipid levels, and increased
waist size—is known to be associated
with elevated risk for heart attack and
stroke. Overall, women who met at least
one of the definitions for metabolic
syndrome were significantly more likely
to experience a cardiovascular event
than those who did not, and there was
no difference between the two
definitions in their predictive ability.
Brown, Vaidya, Rogers, et al., J Womens
Health 17(5):841-847, 2008 (AHRQ
grant HS13852).
- Aspirin therapy to prevent heart attack
may have different benefits and harms
in men and women.
The U.S. Preventive Services Task Force
reviewed new evidence from NIH's
Women's Health Study and other recent
research and found good evidence that
aspirin decreases first heart attacks in
men and first strokes in women. The
Task Force has issued a
recommendation that women between
the ages of 55 and 70 should use aspirin
to reduce their risk for ischemic stroke
when the benefits outweigh the harms
for potential gastrointestinal bleeding.
The recommendation and other
materials are available at
http://www.USPreventiveServicesTaskForce.org/uspstf/uspsasmi.htm.

2007 (AHRQ grant T32 HS00020).
- Women are more likely than men to be
hospitalized for unexplained chest
pain.
Data show that in 2006, there were
477,000 admissions of women to U.S.
hospitals for unspecified chest pain—feeling of pressure, burning, or
numbness—compared with 379,000
admissions for men. Although it is not
clear why women receive this diagnosis
more than men, there is some evidence
that heart disease develops differently in
women and men, and their symptoms
may differ. Go to HCUP Facts and Figures
2006, online at http://www.hcup-us.ahrq.gov/reports/factsandfigures.jsp (Intramural).
- Female and black stroke patients are
less likely than others to receive
preventive care for subsequent strokes.
A third of stroke survivors suffer
another stroke within 5 years, and there
are several therapies to prevent further
strokes in these patients. According to
this study of 501 patients hospitalized
for stroke, 66 percent of women and 77
percent of blacks received incomplete
inpatient evaluations, compared with 54
percent of men and 54 percent of
whites. Also, women were more likely
than men to receive incomplete
discharge regimens (anticoagulants and
other stroke prevention medications and
outpatient followup). Tuhrim,
Cooperman, Rojas, et al., J Stroke
Cerebrovasc Dis 17(4):226-234, 2008
(AHRQ grant HS10859).
- Process-of-care variables may explain
some of the male-female differences in
cardiovascular disease outcomes.
Researchers analyzed seven
cardiovascular disease (CVD) quality of
care indicators in a national sample of
managed care plans and found inadequate lipid control in both men
and women, with a lower rate of control
in women. Also, women with diabetes
were 19 percent less likely than men to
have their LDL cholesterol controlled;
women with a history of CVD were 28
percent less likely than men to have
their LDL cholesterol controlled. More
women than men had their blood
pressure controlled, although the
difference was small (2 percent). Chou,
Scholle, Weisman, et al., Women's Health
Issues 17:120-130, 2007 (AHRQ
contract 290-04-0018).
- Commercial health plans show
disparities between women and men in
cardiovascular care.
Researchers evaluated plan-level
performance of seven quality of care
measures for CVD and found that over
half of the plans showed a disparity of 5
percent or more in favor of men for
cholesterol control measures among
people with diabetes, a recent CVD
procedure, or heart attack. The greatest
disparity (9.3 percent in favor of men)
was among those with recent acute
cardiac events; none of the plans showed
disparities in favor of women.
Disparities between women and men
were even greater among Medicare
managed care plans. Chou, Wong,
Weisman, et al., Women's Health Issues
17:139-149, 2007 (AHRQ contract
290-04-0018). Go to also Bird, Fremont,
Bierman, et al., Women's Health Issues
17:131-138, 2007 (AHRQ contract
290-00-0012).
- Women continue to fare worse than
men in treatment for heart attack and
congestive heart failure.
According to this study of gender
disparities among adults age 65 and
older, women with acute myocardial
infarction (AMI) or congestive heart
failure (CHF) do not receive the same
care as men. Also, women or men who
have other medical conditions associated
with AMI or CHF—such as diabetes,
hypertension, or end-stage renal
disease—do not receive better quality of
cardiovascular care than those who have
only the heart conditions. Correa-de-Araujo, Stevens, Moy, et al., Women's
Health Issues 16(2):44-55, 2006 (AHRQ
Publication No. 06-R042)*
(Intramural).
- Immunosuppression related to
transfusion may explain women's
increased risk of dying after CABG
surgery.
A study of more than 9,000 Michigan
Medicare patients found that women
undergoing coronary artery bypass graft
(CABG) surgery were 3.4 times as likely
as men to have received blood
transfusions and generally received more
units of blood, after accounting for age,
coexisting conditions, and other factors.
Patients who received a transfusion were
more than three times as likely to
develop an infection as those who did
not, and they were 5.6 times as likely to
die within 100 days after surgery. The
presence of foreign leukocytes in donor
blood may suppress the immune system
of the recipient and thus increase the
risk of postoperative infection, note the
researchers. Rogers, Blumberg, Saint, et
al., Am Heart J 152:1028-1034, 2006
(AHRQ grant HS11540).

Cancer Screening and Treatment
Breast cancer continues to be the most
commonly diagnosed cancer among
women in the United Sates. In 2008, an
estimated 182,400 U.S. women were
newly diagnosed with breast cancer, and
more than 40,000 women died from
the disease.
The good news is that breast cancer
deaths have declined recently among
white women in this country; the bad
news is that over the same period,
survival has decreased among black
women. The 5-year breast cancer
survival rate is 69 percent for black
women, compared with 85 percent for
white women.
In 2008, there were an estimated
11,000 newly diagnosed cases of
invasive cervical cancer in U.S. women,
and about 3,900 women died from the
disease. Cervical cancer occurs most
often among minority women,
particularly Asian-American
(Vietnamese and Korean), Alaska
Native, and Hispanic women. Although
deaths from cervical cancer have
declined substantially over the past 30
years, the cervical cancer death rate for
black women continues to be more than
twice that of white women.
Breast Cancer
- Booklet provides helpful information
about breast biopsy.
This guide for women with breast
cancer discusses the different kinds of
breast biopsies, including their accuracy
and side effects. It can help women who
need biopsies talk with their doctors and
nurses about the procedure and what to
expect. Having a Breast Biopsy: A Guide

(AHRQ contract 290-02-0019).
- Guide for women discusses two drugs
used to lower the risk of breast cancer.
Two drugs—tamoxifen and raloxifene—have been approved for the prevention
of primary (first occurrence) breast
cancer in women who have a higher
than average risk of breast cancer. This
guide provides information about the
drugs' benefits, side effects, and cost,
and can help women talk with their
doctors to decide whether one of these
drugs would be right for them. Reducing

- Nonsurgical method for diagnosing
breast cancer found to be safe and
effective.
This AHRQ report compares the safety
and effectiveness of traditional surgical
biopsies with various types of "core
needle biopsy" for diagnosing breast
cancer. Based on a review of scientific
evidence, it shows that certain core
needle biopsies could distinguish
between malignant and benign lesions
approximately as accurately as open
surgical biopsy, commonly considered to
be the gold standard for evaluating
suspicious lesions. The report provides
important information to help
physicians and patients work together to
make the best possible diagnostic choice
for each patient. Comparative

- Less than 15 percent of radiologists say
they definitely would tell a patient
about an error in mammogram
interpretation.
A survey of 243 radiologists at seven
geographically dispersed breast cancer
surveillance sites found that 9 percent of
those surveyed definitely would not
disclose an error in mammogram
interpretation; 51 percent would
disclose the error only if specifically
asked by the patient; 26 percent said
they probably would disclose the error;
and just 14 percent said they definitely
would disclose the error. Neither
concern about the effects that
malpractice is having on the practice of
radiology nor having been sued
previously were associated with
disclosure willingness or disclosure
content. Gallagher, Cook, Brenner, et
al., Radiology 253(2):443-452, 2009
(AHRQ grant HS10591).
- Automated telephone reminders lead to
increased use of mammography.
Researchers tested the effectiveness of
automated telephone reminders (ATRs),
enhanced reminder letters, and standard
letters on the likelihood of repeat
mammograms in 3,547 women who
were randomly assigned to one of the
three groups. The ATRs were found to
be the least costly but most effective (76
percent) intervention for prompting
repeat mammograms compared with
the enhanced (72 percent) and standard
(74 percent) reminder letters. Overall,
74 percent of women had a repeat
mammogram within 10-14 months
compared with 57 percent before the
reminders. DeFrank, Rimer, Gierisch, et
al., Am J Prevent Med 36(6):459-467,
2009 (AHRQ grant T32 HS00079).
- In St. Louis, black women are more
likely than white women to receive
mammograms.
St. Louis, MO, is known to have high
rates of breast cancer diagnosed at a late-stage,
and researchers have been looking
at ways to increase mammography use
in late-stage diagnosis areas. From
March 2004 to June 2006, researchers
conducted a survey of women (429
black, 556 white) older than age 40
living in the St. Louis area.
Unexpectedly, more black women (75
percent) than white women (68
percent) reported that they had received
mammograms. The researchers note
that such geographic clustering of late-stage
breast cancer diagnosis can be
useful in targeting interventions to
increase mammography use. Lian, Jeffe,
and Schootman, J Urban Health
85(5):677-692, 2008 (AHRQ grant
HS14095).
- Radiologists' perception of malpractice
risk appears to be higher than the
actual number of lawsuits.
Researchers mailed a survey in 2002 and
again in 2006 to radiologists in three
States—Washington, Colorado, and
New Hampshire—to determine their perceived risk of facing a lawsuit related
to mammogram interpretation. They
found that the radiologist's perceived
risk of being sued was significantly
higher than the actual number of
reported malpractice cases involving
breast imaging. Radiologists who spent
more time on breast imaging or
interpreting a higher volume of
mammograms did not have a
significantly higher perceived risk of a
lawsuit. Those who felt more at risk
were more likely to have had a
malpractice claim in the past or know of
other radiologists who had been sued.
Dick, Gallagher, Brenner, et al., Am J
Roentgenol 192(2):327-333, 2009
(AHRQ grant HS10591).
- Study finds no correlation between
abnormal mammogram interpretation
and radiologists' job satisfaction.
In this study, 131 radiologists were
surveyed about their clinical practices
and attitudes related to screening
mammography. Performance data were
used to determine the odds of an
abnormal mammogram interpretation.
More than half of the radiologists said
they enjoyed interpreting screening
mammograms; most in this group were
female, older, and working part time;
affiliated with academic medical centers;
and/or on an annual salary. Those who
did not enjoy the work reported it as
being tedious. There were no significant
differences in mammogram
interpretation and cancer detection
between those who did and did not
enjoy their work. Geller, Bowles, Sohng,
et al., Am J Roentgenol 192(2):361-369,
2009 (AHRQ grant HS10591).
- Lack of knowledge and mistrust may
partly explain women's underuse of
adjuvant therapy for breast cancer.
Adjuvant therapies (chemotherapy,
hormone therapy, and radiotherapy)
following breast cancer surgery have
been proven effective in women with
early-stage breast cancer, yet 32 of 258
women in this study who should have
received adjuvant therapy did not get it.
According to practice guidelines, 64 of
the women should have received
chemotherapy, 150 should have received
hormone therapy, and 174 should have
received radiotherapy. The principal
factors associated with lack of adjuvant
treatment were age older than 70,
coexisting illnesses, and mistrust in the
medical delivery system. The researchers
call for better education of women
regarding the benefits and risks of
treatment, as well as straightforward
discussion about issues of trust. Bickell,
Weidmann, Fei, et al., J Clin Oncol
27(31):5160-5167, 2009. Go to also
Bickell, LePar, Wang, and Leventhal, J
Clin Oncol 25(18):2516-2521, 2007

Carlson, J Natl Compr Canc Netw
5(3):349-356, 2007 (AHRQ grant
HS15756); and Fryback, Stout,
Rosenberg, et al., J Natl Cancer Inst
Monographs 36:37-47, 2006 (AHRQ
grant T32 HS00083).
- Tracking system helps to ensure women
with breast cancer see oncologists and
receive followup care.
Some women diagnosed with breast
cancer, especially blacks and Latinos, do
not follow through with their referrals
to an oncologist. To address this
problem, researchers developed a
tracking system to facilitate followup
with breast cancer patients. They
compared the treatment of 639 women
with early stage breast cancer who were
seen at six New York City hospitals
between January 1999 and December
2000 with 300 women who were seen
between September 2004 and March
2006, after the tracking system began.
Rates of oncology consultations,
chemotherapy, and hormone therapy
were higher for all women once the
system was in place, and the racial
disparities in use of care that had existed
were eliminated. Bickell, Shastri, Fei, et
al., J Natl Cancer Inst 100(23):1717-1723, 2008 (AHRQ grant HS10859).
- Study finds that three drugs effectively
reduce risk of breast cancer but may
cause other problems.
Three drugs—tamoxifen, raloxifene,
and tibolone—significantly reduce
invasive breast cancer in middle-aged
and older women who are at risk but
have not previously had breast cancer.
However, each of the three drugs has its
own side effects and risks, and these
must be balanced against the benefits
for an individual patient. For example,
tamoxifen carries an increased risk for
endometrial cancer and blood clots and
has side effects such as flushing, night
sweats, and vaginal dryness. Raloxifene
also carries a risk for blood clots and has
side effects such as flushing and leg
cramps. Tibolone carries an increased
risk of stroke and has side effects that
include vaginal bleeding. Comparative

- Poverty may explain racial disparities
in receipt of chemotherapy for breast
cancer in older women.
According to this study of nearly
14,500 older women with stage II or
IIIA breast cancer with positive lymph
nodes, black women were less likely
than white women to receive
chemotherapy within 6 months of
diagnosis (56 percent vs. 66 percent,
respectively). When the results were
adjusted to include socioeconomic
status for women aged 65 to 69, poverty
appeared to be at the root of the
disparity. Despite Medicare coverage,
out-of-pocket costs—including
copayments, transportation, and so
on—may be overwhelming for women
in the lowest income groups. Bhargava
and Du, Cancer 115(13):2999-3008,
2009 (AHRQ grant HS16743).
- Online support groups seem to benefit
women with metastatic breast cancer.
A group of 20 women (all were white)
with metastatic breast cancer were assigned to one of three online support
groups. The women received a monthly
e-mail questionnaire and after at least 4
months in the support group, each
woman was interviewed for 30 to 90
minutes. Six helpful factors identified in
an earlier study were found to be
present in these groups: group
cohesiveness, universality, information
exchange, instillation of hope, catharsis,
and altruism. Vilhauer, Women Health
49:381-404, 2009 (AHRQ grant
HS10565).
- Behavioral health carve-outs limit
access to mental health services for
women with breast cancer.
Up to 40 percent of women with breast
cancer suffer significant psychological
distress, but only about 30 percent of
them receive treatment for it, according
to this study. Researchers analyzed
insurance claims, enrollment data, and
insurance benefit design data from
1998-2002 on women 63 years of age
or younger with newly diagnosed breast
cancer. They found that women
enrolled in insurance plans with
behavioral health carve-outs were 32
percent less likely to receive mental
health services compared with women
in plans that had integrated behavioral
health services. Azzone, Frank, Pakes, et
al., J Clin Oncol 27(5):706-712, 2009
(AHRQ grant HS10803)
- Journal supplement focuses on
guidelines for international
implementation of breast health and
breast cancer control initiatives.
This journal supplement presents a
series of 15 articles authored by a group
of breast cancer experts and advocates
and presented at the Global Summit on
International Breast Health
Implementation held in Budapest,
Hungary, in October 2007. The articles
focus on guideline implementation for
early detection, diagnosis, and
treatment; breast cancer prevention;
chemotherapy; and other breast health
topics. Cancer 113, Supplement 8, 2008
(AHRQ grant HS17218).
- Several factors affect the accuracy of
mammogram interpretation.
Researchers examined how differences
among mammography facilities affect
the results of mammogram
interpretation. They found that the
most accurate facilities offered screening
but not diagnostic mammograms, had a
breast imaging specialist on staff, and
conducted audits of radiologists'
performance two or more times per
year. Their findings are based on a
review of 5 years of mammogram data
and results of surveys received from 43
facilities and their 128 radiologists in
the Pacific Northwest, New Hampshire,
and Colorado. Taplin, Abraham,
Barlow, et al., J Natl Cancer Inst
100(12):876-887, 2008 (AHRQ grant
HS10591). See also Miglioretti, Smith-Bindman, Abraham, et al., J Natl
Cancer Inst 99(24):1854-1863, 2007
(AHRQ grant HS10591).
- Lesions overlooked on mammograms
represent missed opportunities for early
diagnosis.
Among women with breast cancers that
are diagnosed between routine screening
mammograms, 10 to 20 percent have
lesions that were visible but overlooked
at their previous exam, and a similar
percentage have lesions that were
misinterpreted at the previous exam. In
both cases, the opportunities for early
diagnosis and intervention were missed.
These authors discuss the pros and cons
of double or even quadruple reading of
mammograms and computer-aided
detection as a second digital "reader" of
mammograms. Elmore and Brenner, J
Natl Cancer Inst 99(15):1141-1143,
2007 (AHRQ grant HS10591).
- Requirement for cost-sharing reduces
use of mammography among some
groups of women.
Researchers examined data on
mammography use and cost-sharing
from 2002 to 2004 for more than
365,000 women covered by Medicare.
Of the 174 Medicare health plans
studied, just 3 required copayments of
$10 or more or coinsurance of more
than 20 percent in 2001; by 2004, 21
plans required cost-sharing of one form
or another. The increase in coinsurance
requirements correlated with a decrease
in screening mammograms. Less than
70 percent of women in cost-sharing
plans were screened, compared with
nearly 80 percent of fully covered
women. Although every demographic
group was affected, black women and
women with lower incomes and
educations levels often were covered by
plans that required cost-sharing. Trivedi,
Rakowski, and Ayanian, N Engl J Med
358(4):375-383, 2008 (AHRQ grant
T32 HS00020).
- Breast desmoid tumors are rare and
often mistaken for cancer.
A review over 25 years (1982-2006) at
one institution identified 32 patients
with pathologically confirmed breast
desmoids. Their median age was 45;
eight patients had a prior history of
breast cancer, and 14 had undergone
breast surgery, with desmoids diagnosed
an average of 24 months
postoperatively. All patients presented
with physical findings; MRI was more
accurate in visualizing the mass than
mammography or ultrasound. All
patients had their tumors surgically
removed, and eight patients had
recurring tumors at a median of 15
months. The researchers recommend
that clinical judgment be used before
extensive and potentially deforming
breast resections are performed.

Surg Oncol 15(1):274-280, 2008
(AHRQ grant T32 HS00066).
- More attention is needed to quality of
life for breast cancer survivors.
Researchers examined quality of life
among women with (114 women) and
without (2,527 women) breast cancer.
Women with breast cancer reported
lower scores on physical function,
general health, vitality, and social
function compared with women who
did not have breast cancer. There was no difference in mental health scores
between the two groups of women.

Breast Cancer Res 109:379-387, 2008
(AHRQ grant HS06941).
- Study underway to develop computer-based
tools to improve use of genetic
breast cancer tests.
AHRQ has funded a new project to
develop, implement, and evaluate four
computer-based decision-support tools
that will help clinicians and patients
better use genetic tests to identify,
evaluate, and treat breast cancer. The
first pair of tools will assess whether a
woman with a family history of cancer
should be tested for BRCA1 and
BRCA2 gene mutations. The second
pair of tools, for women already
diagnosed with breast cancer, will help
determine which patients are suitable
for a gene expression profiling test that
can evaluate the risk of cancer
recurrence and whether they should
have chemotherapy. More information
is available online at
http://effectivehealthcare.ahrq.gov
(AHRQ contract 290-200-50036I).
- Report discusses impact of several gene
expression profiling tests for breast
cancer patients.
Breast cancer treatment today often
involves a multi-modality approach,
including surgery, radiation therapy,
endocrine therapy, and/or
chemotherapy. Gene expression
profiling has been proposed as an
approach to assess women's risk of
distant disease recurrence. This report
discusses the available evidence on three
breast cancer gene expression assays: the
Oncotype DX™ Breast Cancer Assay,
the MammaPrint® Test, and the Breast
Cancer Profiling Test. Tests that
improve such estimates of risk

- Noninvasive tests may miss breast
cancer.
This report indicates that four common
noninvasive tests for breast cancer are
not accurate enough to replace biopsies
for women who receive abnormal
findings from mammography or a
clinical breast exam. Researchers found
that each of the four tests—magnetic
resonance imaging (MRI),
ultrasonography (ultrasound), positron
emission tomography scanning (PET
scan), and scintimammography (nuclear
medicine scan)—would miss a
significant number of cases of cancer,
compared with immediate biopsy, in
women at high enough risk to warrant
evaluation for breast cancer. Effectiveness

Abnormalities, Executive Summary No.

- Radiation therapy for a primary
cancer that develops in a second breast
may offer a survival benefit.
Radiation therapy following breast-conserving
surgery (BCS) for a primary
breast cancer reduces the risk of
recurrence, but it has only a small
overall survival benefit. However,
omission of radiation therapy following
BCS for a primary cancer that later
develops in a second breast appears to
double the risk of dying, according to
this study. Researchers compared
mortality rates of women aged 40 to 69
who did not receive radiation therapy
following BCS for the second breast (43
percent of women) with those who did.
Women who did not receive radiation
had slightly more than twice the risk of
dying from breast cancer and 1.7 times
the risk of dying from all causes as
women who received radiation.

- Booklet helps women assess their
treatment options for early-stage breast
cancer.
Women newly diagnosed with early-stage
breast cancer usually can choose
between mastectomy and breast-conserving
surgery (lumpectomy)
followed by radiation. Research has
shown that long-term outcomes are
similar for both treatments. This
booklet provides information to help
women work with their providers to
choose which type of surgery they will
have and, if they choose mastectomy,
whether they want to have
reconstructive surgery. The booklet was
developed collaboratively by the
National Cancer Institute and AHRQ.

- Race, age, and other factors affect
degree of pain among women with
breast cancer.
Researchers studied 1,124 women with
stage IV breast cancer over the course of
a year and found that minority women
who had advanced breast cancer
suffered more pain than white women.
In addition, women who were inactive
and younger women also reported more
severe pain. Castel, Saville, DePuy, et
al., Cancer 112(1):162-170, 2008
(AHRQ grant T32 HS00032).
- Death and complications following
breast cancer surgery are rare.
The most common complication of
breast cancer surgery is wound
infection, which is twice as common
after mastectomy as lumpectomy and
lymph node dissection, according to this
study. Factors that may contribute to
the higher rate of wound infection following mastectomy include extensive
tissue dissection, drain placement,
formation of pockets of fluid, and
longer operation time, as well as a
woman's overall health status.
Researchers analyzed data on 1,660
women (mean age 56) who underwent
mastectomy and 1,447 women who
underwent breast conserving surgery at
14 university and 4 community medical
centers. There were few cardiac or
pulmonary complications in the
mastectomy group and none in the
lumpectomy group; central nervous
system problems were rare in both
groups. El-Tamer, Ward, Schifftner, et
al., Ann Surg 245(5):665-671, 2007
(AHRQ grant HS11913).
- Breast screening is less common in
counties that have many uninsured
women.
Researchers used data from two large
surveillance systems to determine
whether screening for breast cancer
varied by the proportion of uninsured
women in the community. The data
showed that as the rate of uninsurance
in a community increased by 5 percent,
women were 5 percent less likely to
receive either clinical breast exams or
mammograms. Breast cancer screening
declined significantly for women
earning $25,000 to $75,000 who lived
in counties with high rates of
uninsurance. On the other hand, black
women and Hispanic women had
higher screening rates than white
women when they lived in communities
with low rates of uninsurance.

- Women aged 40 to 49 were responsive
to changes in mammography
recommendations.
According to interviews with 1,451
women who received screening
mammograms at one of five hospital-based
clinics between October 1996 and
January 1998, opinions about
mammography have changed among
women aged 40 to 49. Prior to the
issuance of recommendations by the
American Cancer Society and the
National Cancer Institute that women
aged 40 to 49 should receive screening
mammograms every 1 or 2 years, only
49 percent of women in this age group
endorsed annual screening. After the
new recommendations were issued, 64
percent of women in this age group
endorsed annual screening. Calvocoressi,
Sun, Kasl, et al., Cancer 120(3):473-480, 2008 (AHRQ grant HS11603).
- Immediate reading of mammograms
and followup on false-positive results
reduce anxiety among women.
A group of women aged 40 and older
participated in this study at seven sites
in the Boston area between February
1999 and January 2001. Radiologists
read the mammograms of 564 women
immediately, while the films of 576
women were read in batches at a later
time. Although there were more false-positives
in the immediate-reading
group, that strategy provided quick
resolution of false-positives and led to
significantly lower anxiety among those
women. Immediate reading of
mammograms increased costs to health
plans by 10 percent because of reduced
efficiency and the need for extra films.
However, 12-month costs did not differ
significantly between the two groups.

Barton, Health Serv Res 42(4):1464-1482, 2007 (AHRQ Publication No.
07-R067)* (Intramural).
- Depression hinders recovery of older
breast cancer patients.
Researchers examined data on 187
women aged 60 years and older,
including the presence of depressive
symptoms 2 months after breast cancer
diagnosis. They also examined
sociodemographic factors, type of breast
cancer treatment, and shoulder range of
motion at 12 months after diagnosis.
Results showed that each unit increase
in depressive symptoms was associated
with an 8 percent decreased odds of
having full range of shoulder motion a
year after diagnosis. Caban, Freeman,
Zhang, et al., Clin Rehabil 20:513-522,
2006 (AHRQ grant HS11618).
- Poor communication of mammogram
results may explain disparities in breast
cancer diagnosis and outcomes.
Researchers surveyed 411 black and 734
white women who had screening
mammograms at five hospital-based
facilities in Connecticut between 1996
and 1998 and found no difference
between the two groups of women in
the proportion of abnormal screening
mammograms. However,
communication of mammogram results
was problematic for 14.5 percent of the
women; 12.5 percent had not received
their results, and 2 percent had received
their results but their self-report differed
from the radiology record. Inadequate
communication of mammogram results
was nearly twice as common among
black women as among white women.

- Physician communication style may
depend on characteristics of breast
cancer patients.
According to this study, oncologists tend
to communicate differently with women
newly diagnosed with breast cancer,
depending on their age, race, education,
and income. A series of videotaped visits
between 58 oncologists with 405
women revealed that the physicians
spent more time engaged in building
relationships with white women than
with women of other races; the same
was true of visits with more educated
and affluent patients compared with less
advantaged patients. The women who
asked more questions tended to be
younger, white, better educated (beyond high school), and more affluent than
other patients. Siminoff, Graham, and
Gordon, Patient Educ Counsel 62:355-360, 2006 (AHRQ grant HS08516).

- Task Force revises recommendations for
mammography.
The U.S. Preventive Services Task Force
updated its recommendation by calling
for screening mammography, with or
without clinical breast exam, every 1 to
2 years for women 40 and over. The
recommendation acknowledges some
risks associated with mammography,
which will lessen as women age. The
strongest evidence of benefit and
reduced mortality from breast cancer is
among women ages 50 to 69. The
recommendation and materials for
clinicians and patients are available at
